Becoming A Food Citizen, Nicole Hornung Jan 2013

Becoming A Food Citizen, Nicole Hornung

Electronic Theses and Dissertations

Environmental citizenship is positioned as a platform where the rights of social and environmental justice converge with civic engagement and responsibility. As industrialized economies continue to exhaust the limits of finite natural resources and exacerbate conditions of global climate change, scholars have questioned if environmental citizenship models offer a method for deepening obligations to a sustainable movement. In the material culture enjoyed by Western civilizations, existing research supports that an individual’s purchases are seen as an indicator of their values and identities. Consequently the commitment to responsible buying behavior or sustainable consumption is in a sense an expression of eco-citizenship. …

For Alexander: An Exploration Of Good Ole Boy Identity And Mortality., Chad Johnson Jan 2013

For Alexander: An Exploration Of Good Ole Boy Identity And Mortality., Chad Johnson

Electronic Theses and Dissertations

"For Alexander" is an exhibition about masculinity as it is exhibited by Southern "good ole boys". I rely on original and appropriated imagery, as well as memories of loss and humor from my childhood in Alabama. Combining mixed media and sculptural elements has allowed me to investigate the subjects that interest me. I explore and artistically comment on these subjects through a mix of personal and culturally loaded imagery that records what I have either experienced or researched, and which I realize through the ironic use of non-traditional materials, such as sequins and rhinestones. My work examines stereotypes and my …

Tracking Violence: Using Neighborhood-Level Characteristics In The Analysis Of Domestic Violence In Chicago And The State Of Illinois, Rachel Morgan Jan 2013

Tracking Violence: Using Neighborhood-Level Characteristics In The Analysis Of Domestic Violence In Chicago And The State Of Illinois, Rachel Morgan

Electronic Theses and Dissertations

Social disorganization theory proposes that neighborhood characteristics, such as residential instability, racial and ethnic heterogeneity, concentrated disadvantage, and immigrant concentration contribute to an increase in crime rates. Informal social controls act as a mediator between these neighborhood characteristics and crime and delinquency. Informal social controls are regulated by members of a community and in a disorganized community these controls are not present, therefore, crime and delinquency flourish (Sampson, 2012). Researchers have focused on these measures of social disorganization and the ability to explain a variety of crimes, specifically public crimes. Recently, researchers have focused their attention to characteristics of socially …

Chemophysical Characteristics And Application Of Biosorption Activated Media (Bam) For Copper And Nutrient Removal In Stormwater Management, Jamie Jones Jan 2013

Chemophysical Characteristics And Application Of Biosorption Activated Media (Bam) For Copper And Nutrient Removal In Stormwater Management, Jamie Jones

Electronic Theses and Dissertations

For high groundwater table areas, stormwater wet detention ponds are utilized as the preferred stormwater management throughout the state of Florida. Previous research has found that accumulations of nutrients, algae, heavy metals, pesticides, chlorophyll a, fecal coliform bacteria and low concentrations of dissolved oxygen (DO) are common characteristics of stormwater wet detention ponds. Although these pollutant levels are not regulated within the ponds, states are required to compute the pollutant load reductions through total maximum daily load (TMDL) programs to meet the water quality requirements addressed by the Clean Water Act (CWA). In this study, field sampling data of stormwater …

Integrated Data Fusion And Mining (Idfm) Technique For Monitoring Water Quality In Large And Small Lakes, Benjamin Vannah Jan 2013

Integrated Data Fusion And Mining (Idfm) Technique For Monitoring Water Quality In Large And Small Lakes, Benjamin Vannah

Electronic Theses and Dissertations

Monitoring water quality on a near-real-time basis to address water resources management and public health concerns in coupled natural systems and the built environment is by no means an easy task. Furthermore, this emerging societal challenge will continue to grow, due to the ever-increasing anthropogenic impacts upon surface waters. For example, urban growth and agricultural operations have led to an influx of nutrients into surface waters stimulating harmful algal bloom formation, and stormwater runoff from urban areas contributes to the accumulation of total organic carbon (TOC) in surface waters. TOC in surface waters is a known precursor of disinfection byproducts …

Routing, Localization And Positioning Protocols For Wireless Sensor And Actor Networks, Mustafa Akbas Jan 2013

Routing, Localization And Positioning Protocols For Wireless Sensor And Actor Networks, Mustafa Akbas

Electronic Theses and Dissertations

Wireless sensor and actor networks (WSANs) are distributed systems of sensor nodes and actors that are interconnected over the wireless medium. Sensor nodes collect information about the physical world and transmit the data to actors by using one-hop or multi-hop communications. Actors collect information from the sensor nodes, process the information, take decisions and react to the events. This dissertation presents contributions to the methods of routing, localization and positioning in WSANs for practical applications. We first propose a routing protocol with service differentiation for WSANs with stationary nodes. In this setting, we also adapt a sports ranking algorithm to …

Bio-Inspired, Varying Manifold Based Method With Enhanced Initial Guess Strategies For Single Vehicle's Optimal Trajectory Planning, Ni Li Jan 2013

Bio-Inspired, Varying Manifold Based Method With Enhanced Initial Guess Strategies For Single Vehicle's Optimal Trajectory Planning, Ni Li

Electronic Theses and Dissertations

Trajectory planning is important in many applications involving unmanned aerial vehicles, underwater vehicles, spacecraft, and industrial manipulators. It is still a challenging task to rapidly find an optimal trajectory while taking into account dynamic and environmental constraints. In this dissertation, a unified, varying manifold based optimal trajectory planning method inspired by several predator-prey relationships is investigated to tackle this challenging problem. Biological species, such as hoverflies, ants, and bats, have developed many efficient hunting strategies. It is hypothesized that these types of predators only move along paths in a carefully selected manifold based on the prey’s motion in some of …

Evaluation Of The Biodegradability And Toxicity Of Pca And Mpca, Juan Rueda Jan 2013

Evaluation Of The Biodegradability And Toxicity Of Pca And Mpca, Juan Rueda

Electronic Theses and Dissertations

The main types of hypergolic propellants used at Kennedy Space Center (KSC) are hydrazine (HZ) and monomethylhydrazine (MMH). HZ and MMH are classified as hazardous materials and they are also known to be potentially carcinogenic to humans; therefore, handling these substances and their waste is strictly regulated. The wastes streams from HZ and MMH have been estimated to be the main hazardous wastes streams at KSC. Currently at KSC these wastes are first neutralized using citric acid and then they are transported on public roads for incineration as hazardous materials. A new method using alpha ketoglutaric acid (AKGA) was proposed …

Virtual Interactions With Real-Agents For Sustainable Natural Resource Management, Tyler Pierce Jan 2013

Virtual Interactions With Real-Agents For Sustainable Natural Resource Management, Tyler Pierce

Electronic Theses and Dissertations

Common pool resource management systems are complex to manage due to the absence of a clear understanding of the effects of users’ behavioral characteristics. Non-cooperative decision making based on individual rationality (as opposed to group rationality) and a tendency to free ride due to lack of trust and information about other users’ behavior creates externalities and can lead to tragedy of the commons without intervention by a regulator. Nevertheless, even regulatory institutions often fail to sustain natural common pool resources in the absence of clear understanding of the responses of multiple heterogeneous decision makers to different regulation schemes. While modeling …

Near-Road Dispersion Modeling Of Mobile Source Air Toxics (Msats) In Florida, Kurt Westerlund Jan 2013

Near-Road Dispersion Modeling Of Mobile Source Air Toxics (Msats) In Florida, Kurt Westerlund

Electronic Theses and Dissertations

There is a growing public concern that emissions of mobile source air toxics (MSATs) from motor vehicles may pose a threat to human health. At present, no state or federal agencies require dispersion modeling of these compounds, but many agencies are concerned about potential future requirements. Current air pollution professionals are familiar with Federal Highway Administration (FHWA) and U.S. Environmental Protection Agency (EPA) requirements for dispersion modeling to produce predicted concentrations for comparison with appropriate standards. This research examined a method in which the potential near-road concentrations of MSATs were calculated. It was believed that by assessing MSATs in much …

Automatically Acquiring A Semantic Network Of Related Concepts, Sean Szumlanski Jan 2013

Automatically Acquiring A Semantic Network Of Related Concepts, Sean Szumlanski

Electronic Theses and Dissertations

We describe the automatic acquisition of a semantic network in which over 7,500 of the most frequently occurring nouns in the English language are linked to their semantically related concepts in the WordNet noun ontology. Relatedness between nouns is discovered automatically from lexical co-occurrence in Wikipedia texts using a novel adaptation of an information theoretic inspired measure. Our algorithm then capitalizes on salient sense clustering among these semantic associates to automatically disambiguate them to their corresponding WordNet noun senses (i.e., concepts). The resultant concept-to-concept associations, stemming from 7,593 target nouns, with 17,104 distinct senses among them, constitute a large-scale semantic …

Nano-Particles In Multi-Scale Composites And Ballistic Applications, Jason Gibson Jan 2013

Nano-Particles In Multi-Scale Composites And Ballistic Applications, Jason Gibson

Electronic Theses and Dissertations

Carbon nanotubes, graphene and nano sized core shell rubber particles have all been extensively researched for their capability to improve mechanical properties of thermoset resins. However, there has been a lack of research on their evaluation for energy absorption in high velocity impact scenarios, and the fundamental mechanics of their failure mechanisms during highly dynamic stress transfer through the matrix. This fundamental research is essential for laying the foundation for improvement in ballistic performance in composite armor. In hard armor applications, energy absorption is largely accomplished through delamination between plies of the composite laminate. This energy absorption is accomplished through …

Illegitimate Celebrity In The British Long Eighteenth Century, Melissa Wehler Jan 2013

Illegitimate Celebrity In The British Long Eighteenth Century, Melissa Wehler

Electronic Theses and Dissertations

In the discussions about contemporary celebrities, the femme fatale, the bad boy, the child star, and the wannabe have become accepted and even celebrated figures. In the late eighteenth and early nineteenth centuries, however, actors and actresses who challenged acceptable strategies for celebrity behavior were often punished by exile, debt, disgrace, and humiliation. Some performers even faced a veritable textual and historical oblivion. Illegitimate Celebrity considers the careers of Dorothy Jordan, William Henry West Betty, Edmund Kean, and Margaret Agnes Bunn, and offers a historical genealogy of "illegitimate" performers who dared to break with social convention and struggled to define …

Emotional Intelligence Of Entrepreneurs, Eric P. Swift Jan 2013

Emotional Intelligence Of Entrepreneurs, Eric P. Swift

Electronic Theses and Dissertations

Entrepreneurship benefits the individual and society, but it was unclear whether emotional intelligence (EI) predicts entrepreneurial outcomes. New ventures fail at a high rate. A possible factor in the success or failure of small business could be the emotional intelligence (EI) level of the entrepreneur, defined as the ability to perceive, use, understand, and manage emotions. However, few studies to date had empirically explored EI and entrepreneurship or investigated the predictive value of EI in important measures of entrepreneurial outcomes, such as the success rate in starting new businesses, business longevity, and business profitability. The present study was designed to …

Evaluation Of Dna Barcoding As A Technique For Elucidating The Diet Of Louisiana Waterthrush Nestlings, Brian K. Trevelline Jan 2013

Evaluation Of Dna Barcoding As A Technique For Elucidating The Diet Of Louisiana Waterthrush Nestlings, Brian K. Trevelline

Electronic Theses and Dissertations

The Louisiana Waterthrush (Parkesia motacilla) (LOWA) is a Neotropical-Nearctic migrant songbird that annually breeds in the Eastern United States. As an obligate riparian species, it preys upon a diverse community of benthic macroinvertebrates along headwater streams. Fecal material potentially contains residual DNA that can be used to molecularly identify prey species. The objective of this study was to develop a non-invasive technique capable of elucidating the diet of Waterthrush nestlings from residual DNA present in fecal sacs via DNA barcoding. Our limited analysis revealed that the majority of the analyzed fecal sacs were comprised of an acid-sensitive family of Ephemerotperan …

The Rhetorical Turn In United States Diplomacy Praxis: Public Diplomacy 2.0, Randy Edward Cole Jan 2013

The Rhetorical Turn In United States Diplomacy Praxis: Public Diplomacy 2.0, Randy Edward Cole

Electronic Theses and Dissertations

While discourse and rhetoric has always been a part of traditional diplomacy, rhetoric and communication theory has not enjoyed an active voice in the scholarship of foreign relations, and more specifically, public diplomacy. This project argues that a postmodern turn in public diplomacy was formalized in the State Department's 2010 Quadrennial Diplomacy and Development Review (QDDR) and that two specific directives laid out therein--to expand and strengthen relationships between individuals and steer the narrative--can find theoretical ground in communication scholarship. After examining the mid-to-late 20th century shift from specialized modern policy training to a rhetorical public diplomacy that views diplomats …

Potential Natural Product Phosphodiesterase Inhibitors, Michael John Cunningham Jan 2013

Potential Natural Product Phosphodiesterase Inhibitors, Michael John Cunningham

Electronic Theses and Dissertations

Three different studies set forth to investigate the role of phosphodiesterase (PDE) enzyme inhibitors in sexual dysfunction and mood regulation. First, naturalproducts were screened by computer modeling of PDE5A1. Second, compounds were isolated from a plant traditionally used as an aphrodisiac. Third, a new synthesis of psychoactive PDE4 inhibitor was attempted. An in silico screen was performed using chemical structures of isolated compounds thought to have some PDE inhibitory activity based on traditional use of the plants. A collection of compounds with structures similar to known natural product inhibitors was also included in the docking library. Glide docking software (Schrödinger) …

Large Eddy Simulation Of Surface Pressure Fluctuations Generated By Elevated Gusts, Jericho Erin Cain Jan 2013

Large Eddy Simulation Of Surface Pressure Fluctuations Generated By Elevated Gusts, Jericho Erin Cain

Electronic Theses and Dissertations

Wind gusts cause substantial damage to wind turbines. If these damaging winds could be detected prior to their interaction with the turbine, the turbine rotor can be decoupled from the generator and gearing system to prevent damage during the gust event. This would significantly reduce wind turbine repair costs. Wind gusts can also create unsafe conditions for aircraft landing. A ground based detection system that monitored elevated wind gusts can provide new information for pilots to use when determining whether or not it is safe to land. In addition, the ability to monitor elevated gust events would provide a new …

Bacterial Assemblages And Microbial Enzyme Activity In The Major Tributaries Of The Lower Mississippi River, Justin Millar Jan 2013

Bacterial Assemblages And Microbial Enzyme Activity In The Major Tributaries Of The Lower Mississippi River, Justin Millar

Electronic Theses and Dissertations

Spatial variation in the structure and function of bacterial communities is far more complex than previously believed. High throughput sequencing techniques have begun to elucidate the dynamic worldwide patterns of bacterial biogeography; however, there are still many ecosystems for which there is little to no representative data. Currently there are no high throughput-based analyses of bacterial assemblages in large rivers. Rivers form important connections between terrestrial land use and marine biogeochemistry and act as conduits for organisms and allochthonous nutrients. Bacteria dominate carbon cycling and nutrient processing in rivers, and therefore can influence regional and global elemental cycles. This study …

Benzo[A]Pyrene Effects On Fundulus Heteroclitus Reproductive Endpoints, Frank Booc Jan 2013

Benzo[A]Pyrene Effects On Fundulus Heteroclitus Reproductive Endpoints, Frank Booc

Electronic Theses and Dissertations

Benzo[a]pyrene (BaP) is a polycyclic aromatic hydrocarbon (PAH) that modulates aromatase enzyme function and, thus, potentially interrupts normal reproductive function. The aim of this study was to use a fish model, Fundulus heteroclitus, to assess whether BaP exposure adversely impacted reproduction. Adult fish were exposed to waterborne BaP concentrations of (0, 1 or 10 μg/L) for 28 days. Males and females were combined for the second half of the exposure (days 14-28) in order to quantitate egg production and fertilization success. Egg fertilization and subsequent hatching success of F1 embryos was significantly decreased by 10 μg/L BaP. In males, both …

Home Sweet Home: An Infinite Grid Of Memory And Repressed Abuse Trauma, Melissa Bush

Electronic Theses and Dissertations

Incorporating traditional craft mediums of crochet and embroidery, I use digital technology to experiment with wording to graphically represent my abuse trauma. Due to the severity of the subject matter and the work ethic I employ in my art practice, using my hands and being completely involved is a form of masochistic pleasure. My process takes on a Sisyphean approach of penance for the sins of others in my work. During my studio practice, my process reaches a meditative state where my mind is clear and free of the burden. Once I've completed a panel of trauma, the burden is …

The Epitome And Portrait Of Modern Society: Ouida As Social Barometer Of The Victorian Era, Lorraine Michelle Dubuisson Jan 2013

The Epitome And Portrait Of Modern Society: Ouida As Social Barometer Of The Victorian Era, Lorraine Michelle Dubuisson

Electronic Theses and Dissertations

The Victorian Era was one of great social flux; tremendous advances in science and technology called into question deeply held religious beliefs while the changing legal status of women threatened to undermine traditional views of gender roles. Industrialization and the driving economic force of capitalism led to rapid urbanization as well as contributing to shifting class boundaries. In addition, the purpose and responsibilities of the Artist/Poet and, indeed, of art itself were closely scrutinized and hotly contested. Most frequently, historians and scholars of literature have looked to authors such as Charles Dickens, George Eliot, Oscar Wilde, and Alfred, Lord Tennyson …

Laughing Matters, Matthew Moore Jan 2013

Laughing Matters, Matthew Moore

Electronic Theses and Dissertations

This thesis defends a weak version of the superiority theory of humor: the superiority theory explains some instances of humor better than the incongruity theory. This thesis features an overview of the philosophy of humor in ancient, modern, and contemporary philosophy; this section contains criticisms of the incongruity theory. Connections between the superiority theory and humor about death are explored. Parallels are then drawn between this type of humor and Aristotle's great-souled man. A new type of laughter, jubilant laughter, is subsequently identified as being similar to laughter classified under the superiority theory since both exhibit a triumphant quality. But …

Panpsychism And Mind-Dust, John Heath Hamilton Jan 2013

Panpsychism And Mind-Dust, John Heath Hamilton

Electronic Theses and Dissertations

It is only recently that panpsychism has emerged as a viable position in philosophy of mind and metaphysics. As such, the exploration and defense of it is not yet on par with some competing views. The current project is a step towards a remedy to this unfortunate state of affairs. It concerns one of the most important objections to the view, which I label the 'mind-dust' objection in homage to William James. It is essentially the conceptual difficulty of how proto-experiential being at the micro-level is supposed to 'sum' in a way that forms the consciousness with which we are …

Intersection(S) Between Sociocultural Knowledge, Classroom Discourse And Stance, John Munyui Muchira

Electronic Theses and Dissertations

Speakers of all languages align their talk to that of their peers in order to create identity in social discourse. While students' interactions in class reveal awareness of their personal educational achievements, they also exhibit a desire to inform others about their socio-cultural knowledge, their beliefs, and feelings. A number of studies have shown how participants create interactional environments where they can not only expand their knowledge in instructional styles but to a great extent construct and reconstruct their personas. Sociocultural knowledge and stancetaking has a great impact on classroom discourse and language learning. My study was conducted on an …

Psychotherapy As Constitutional Practice: A Detailed Interaction Analysis Of The Change Process In Psychotherapy, Cody L. Maddox Jan 2013

Psychotherapy As Constitutional Practice: A Detailed Interaction Analysis Of The Change Process In Psychotherapy, Cody L. Maddox

Electronic Theses and Dissertations

Psychotherapy is concerned with changing individuals: it is a practice devoted to the constitution of certain kinds of subjects. Although the various therapeutic schools have their own explanations of psychotherapeutic change, more empirical work needs to be dedicated to understanding how this process takes place. In this study, a fine grain research methodology is used to produce an account of the change process that occurred over the course of two psychotherapy sessions. The data consists of naturally occurring video recordings of a single therapist and client dyad. The goal of this research is to examine the relationship of mutual formation …

Cavitation In Pharmaceutical Manufacturing And Shipping, Donn Sederstrom Jan 2013

Cavitation In Pharmaceutical Manufacturing And Shipping, Donn Sederstrom

Electronic Theses and Dissertations

Therapeutic proteins are used to successfully treat hemophilia, Crohn's Disease, diabetes, and cancer. Recent product recalls have occurred because of sub-visible particle formation resulting from the inherent instability of proteins. It has been suggested that particle formation is associated with late stage processing steps of filling, shipping, and delivery. Previous work at the University of Denver demonstrated that fluid cavitation can generate a large number of sub-visible protein particles in ultra clean formulations, but that mitigation can be achieved with fluid property manipulation. The goal of this research was to (1) assess the risk of cavitation under common pharmaceutical manufacturing …
